I have an issue with my newly acquired 73 super, cannot idle it when warm. Tried almost everything, without dismantling the carb.
Spark plugs/gap .026", point .016". Timing set at 5 ATDC with test light. Cleaned carb with carb cleaning fluid. Even checked electric choke and set it early morning. What could be the cause????
Yesterday test drove it 200 kms at it did show some sign of missing. Highways speed was in between 65-80 MPH, most of the journey was uneventful but did notice a lot of it during the last 15-20 kms.
